l fsnrINGIiF i 'V 'Animation sied aligns@ 3o, y1926. 'seminal 13ans; f f f 1r' This invention"relates to'composition 'shingles, and'yhas forone ofgits objects providing shingles of 4such shape that theyv may be conveniently cut without waste from sheets of 5 shingle material, and canv be assembled upon the roof in such a manner as -to presenta novel and pleasing appearance. Another object is to provide improved means lfor locking down the lap or exposed portion of the shingles so as to eliminate the tendency of the edges thereof to turn upwardly under the stress of weather,

the warping tendency of the sun, or otherwise.

Another object is to fulfill the foregoing conditions and also to reduce the amount of lapping required in order to properly protect the roof.

Of the accompanying drawings Fig. 1 is a plan view of a sheet of shingle material showing how the shingles, which embody the features of my invention, are cut lfrom the sheet without waste; Fig. 2 is a plan view of a number ofshingles indicating their appearance when assembled on the roofgand Fig. 3 is a plan view ofA an Vindividual shingle, somewhat enlarged.

The shingles 4 whenassembled on the roof are normally placed in horizontal rows 5,

though this is not essential to my invention'.

The shingles in the rows have their adjacent ends lapped and the rows themselves are lapped on the adjacent underlying rows. This lapping in either case may be as much as is desired, but the amount of lapping is determined by the particular shape of the shingle.

In forming the shingles I provide adjacent the lower edge thereof slits or slots 6. This slit is in the exposed or lap portion of the shingle' and the purpose of the slit is to lock the lap 8 of the shingle down. This is accom- 40 plished by means of a luga or lock 7 in an adjacent underlying shingle',"the lug 7 passing upwardly through the slit 6, and then proj ecting downwardly and thus lock-ing down the lap portion of theshingle. The amount of lapping of one row upon -the other is determined by the positions of the slits 6 or the lugs 7. By having the lug 7 nearer the lower edge, or having the slit 6 farther from the lower edge, the lapping of the rows will be greater.

Similarly with reference to the end lapping of the adjacent shingles in the rows. This will depend upon the length of the shingles andA particularly the distance the end 9 projects bevond the slit 6. Hence the amount of ent with proper protection.

It willy be not-iced that the endsjoftheshingle's are offset', thepurpose being to' posi-tion assrsfrroa` To A:Siorti/neusthe lug 7 properly,l and to makea single lug at Y one end of the shingle 'to take' the place of two similar lugs, one-,half the sizeof a single lug, one oneach end of theshinglfewA This simpli- 'fies the shingles-and lthelayiug thereof. y*In order to conveniently cut the shingles without waste the .edges of the two ends are made broken as indicated and homologous. However, the exact form of these edges is not ma` terial to my invention. The corners 10 and 11 might be made oblique either obtuse or acute, and other modifications mightbe made. in the shape of the shingle by those skilled in the art without'departing from the spirit of' my invention as-disclosed by the following claims.

In order to more completely cover the vlapped ends of the shingle I the projecting lap 8 is formed, this portion lapping over the ends of the underlying shingles inthe adjacent vlower row. And in order to cut the shingles without waste this lap is made substantially one-half vas long as the main body of the shingle, the lap 8 of one shingle being cut from the body of two adjacent shingles so as toform therein the recesses 12. v v

I claim as my invention: l. A rectangularly shaped flat, tion shingle, a rectangularly shaped lap projecting from the central portion of one side edge, said lap having a slit in its central portion, and a lug fixed to the central portion of an Aend edge of said shingle, said lug being adapted to enter into a slit of a similar shingle.

2. A shingle having-the shape of a paral.- l

lelogram and having an interior longitudinal slit in the central portion of one side adjacent the edge, and alug fixed to the central portion of one end only, thelug being adapt'- ed to ente`r a similar slit in a similar shingle,

composisoV the slits of the adjacent overlapping row, and with 'the lapping ends of the adjacent shingles in the saine row having broken butl homologous edges.

4. A shingle having the general shape of a parallelogram and having a lap projecting from one edge, said lap having an interior slit therein spaced from the outer edge of the lap, and said shingle having a lug fixed to an end of the shingle and projecting outwardly in the plane of the shingle beyond the end edge and adapted to enter a slit of another similar shingle Whenasseinbled on a roof.

5. A plurality of shingles assembled on a roof in overlapping rows, each of the shingles having an inner slit in the central lower por; tion of its exposed lap, and a lug vfixed to an edge of the s i the adjacent shingle in the `same row and .hand ingle at the joint formed with A from one edge, said lap having an interior slittheren spaced from the outer edge of the lap, and said shingle having a lug Xed to an end of the shingle andV projecting outwardly beyond the end yedge and adapted to entera slit of another .similar shingle when asserny bledvon a roof, said lug also extending in- .wardly of said end edge a material distance.
